One of the key elements used in the industry of the electronics is the switches. The various different types of tasks for which the switches are used include providing the power supply to a circuit and selection of a specific element for the circuit which will be used in a given specific application or operation.


The electronics industry uses various different styles and types of inductors. Inductors are used in a circuit in order to perform many functions of various different styles.


The thermistor name has been devised as a short form for the “thermally sensitive resistor”. The full form of the thermistor provides the general and the detailed idea of the action which is the feature of the thermistor.

Types of Resistors

The industry of electronic circuits uses resistors of various different types available in the market. The properties of these resistors vary and are different for each type being ruled by their manufacturing and construction process.

Types of Capacitors Explained

In this post we learn regarding the basics of capacitor, and also regarding the various types of capacitors which are commonly available in the market and used in most electronic circuits.

Color Codes of Resistors

The post comprehensively explains regarding the various standard resistor color codes, and systems employed for assigning resistors their specific values. The post also explains how to read and identify resistor values from their color codes.

How Flex Resistors Work

As electronics enthusiasts we may come across many kinds of resistors, from small fixed resistor to high current bulk rheostat. There are humongous classifications among resistors, but here we will focus on a particular kind of resistor called “flex resistor” and learn how it works.

Understanding Capacitor Codes and Markings

The article comprehensively explains everything about capacitor codes and markings through various diagrams, which can be used for identifying and selecting capacitors correctly for a given circuit application. 

Power Line Communication Appliance Remote Control Circuit

This little circuit will enable a remote controlled switching of an appliance situated in the next room using the concept of power line communication, which involves the use of home mains wire for transferring data in the form of high frequency pulses through the mains wire, superimposed over the existing mains frequency.

How PNP Transistors Work

In this post we learn regarding how a PNP transistor works or conducts in response to a fixed biasing voltage and a varying supply voltage, across its base and emitter. The question was put forth by Mr. Aaron Keenan.
